  • Tillage tools lying rows of discs are arranged.
  • the soil cultivation tools have at least a first tool area and a second tool area and the first tool area wears more than the second tool area due to its exposed arrangement.
  • the invention also relates to a method for producing such a soil cultivation device.
  • the present invention relates generally to a soil cultivating implement which can be pulled over the ground with a drawbar behind a tractor in order to work the ground.
  • the soil cultivation device can be a cultivator, the invention described below also being applicable to similar soil cultivation devices, ie soil cultivation devices with a similar structure and / or a similar arrangement of soil cultivation tools, for example plows.
  • the soil cultivation device is carried by a height-adjustable chassis that can also be used to transport the soil cultivation device in a transport position over public paths and roads between different locations.
  • Mechanisms generally known for such tillage tools for example traction amplifiers, in which the force or weight distribution between tractor and tillage device can be set or changed, folding mechanisms, by means of which a width of the tillage device is reduced to a value permissible for public roads or to a value for tillage efficient value can be increased and additional tools such as leveling tools, rollers, harrows and the like can be particularly advantageous in connection with the present invention.
  • the invention is therefore particularly suitable for such soil cultivation devices which have corresponding mechanisms.
  • a soil cultivation device with wing share cultivator tines is known in which the individual cultivator tines are attached to a three-row frame and distributed over the frame area defined by the edge of this frame.
  • wing share cultivators or similar tillage implements it can be observed that the tillage tools, i.e. The wing shares, for example, do not wear out evenly because they are unevenly stressed.
  • cultivators and similar tillage devices are basically known, in which in addition to loosening the soil in the working direction in front of the Soil cultivation tools, e.g. cultivator shares, concave discs, cutting discs or similar disc tools are used. Conventionally, they are used, among other things, to prepare the soil for cultivation by the cultivator shares, for example by loosening or clearing plant residues.
  • the disc tools are arranged largely independently of the subsequent soil cultivation tools.
  • the soil cultivation tools are arranged in one or more rows of tools that follow one another in the working direction and are oriented transversely to the working direction.
  • the soil cultivation device furthermore has a number s of disc tools, which are arranged in one or more rows of discs that follow one another in the working direction, are oriented transversely to the working direction and lie in front of the soil working tools in the working direction.
  • Each of the disc tools has an individual lateral disc distance from a central longitudinal axis of the soil cultivation device. In the present context, the distance between the slices is always the distance between the in the cutting area of the disc tool engaging the soil in relation to the central longitudinal axis of the soil cultivation device is meant.
  • the soil cultivation tools have at least a first tool area and a second tool area, the first tool area being designed and arranged such that it wears more than the second tool area when the soil cultivation tool is used. In other words, due to its exposed arrangement, the first tool area wears more than the second tool area.
  • the first tool area of each of the soil cultivation tools has an individual first lateral tool distance or several individual first lateral tool distances from the central longitudinal axis of the soil cultivation device and the second tool region of each of the soil cultivation tools has an individual second lateral tool distance from the central longitudinal axis of the soil cultivation device, which deviates from the individual first tool distance .
  • first and second tool areas which can be individually or both in several parts, can be defined for each individual soil cultivation tool and there is a first tool spacing for the first tool area for each individual soil cultivation tool. If the first tool area is made up of several parts, there are of course several first tool clearances, each corresponding to the individual tool subareas. There is also a second tool spacing for the second tool area for each individual soil cultivation tool. If the second tool area is made up of several parts, there are in turn several second tool spacings, each corresponding to the individual tool subareas. Since the soil cultivation tools have different distances from the central longitudinal axis, the first and second tool distances for different soil cultivation tools are also different with different distances. According to the invention, the disc tools and the soil cultivation tools are arranged in such a way that each first tool area has a first lateral tool spacing
  • Disk tool is assigned to the lateral disk spacing in such a way that the first lateral tool spacing is equal to the lateral disk spacing.
  • a disc tool that has the same lateral distance from the central longitudinal axis as the otherwise more heavily worn area.
  • Soil tillage tool locally on the first tool area which would otherwise wear out more, can be reduced. This is possible because the disc tool can loosen the soil and thus reduce its wear and tear. Since the wear effect is reduced locally at those points which would otherwise lead to increased wear of the soil cultivation tools, the soil cultivation tools wear correspondingly more evenly and overall also more slowly. This enables longer service lives and thus lower operating costs.
  • An alternatively defined soil cultivation device with soil cultivation tools, which can in particular be tine tools such as wing share cultivator tines or goose foot share cultivator tines, has a number n of soil cultivation tools which are arranged in one or more rows of tools that follow one another in the working direction and are oriented transversely to the working direction , and has a number s of disc tools, which are arranged in one or more rows of discs that follow one another in the working direction, are oriented transversely to the working direction and lie in front of the soil tillage tools in the working direction.
  • the soil cultivation tools have at least a first tool area and a second Tool area and the first tool area is designed and arranged in such a way that it wears more heavily than the second tool area when the soil cultivation tool is used. In other words, due to its exposed arrangement, the first tool area wears more than the second tool area.
  • the disc tools and the soil cultivation tools are arranged in such a way that a disc tool is assigned to each first tool area in such a way that the first tool area is aligned behind the disc tool in the working direction.

  • the tillage tools are wing share cultivator tines or goosefoot cultivator tines, which have a share tip and two wings each with a wing end, the share tip and the two wing ends forming the first tool area and the wings, i. a region of the wings that is inner opposite the wing tips, forming the second tool region.

  • the share tip is the only first tool area, while other parts of the soil cultivation tool are less exposed to wear. This is the case, for example, if only the share tip of a wing share cultivator tine or goose foot share cultivator tines wears particularly heavily, but the wing tips less because of their overlap or for other reasons wear out more than the point of the share. This can also be due to the fact that the share point also has to cut open the ground, while the wing tips are not exposed to this load.

  • the number s of disc tools is one greater or smaller than the number n of Tillage tools.
